The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.

A method for transferring molten metal from one structure to another includes a cavity constructed inside of or next to a vessel used to retain molten metal. The cavity is divided into a first section and a second section by a wall, wherein the second section includes an uptake section configured to allow molten metal to move upwards, and includes a molten metal pump. The cavity is in fluid communication with the vessel so molten metal from the vessel can enter the cavity through an opening. The pump is operated to move molten metal up upwards in the intake section and through an outlet.

A system for feeding molten metal provided by a feeding component to a receiving component. The system comprises a launder circuit having an upstream end and a downstream end and a flow path fluidly connecting the upstream end to the downstream end, wherein the feeding component feeds the launder circuit with molten metal at the upstream end and the launder circuit feeds molten metal to the receiving component at the downstream end. The system also comprises a feed tilting mechanism located at the upstream end for tilting the feeding component between a holding angle for holding molten metal in the feeding component and a feeding angle for feeding molten metal to the launder circuit, a feeding scale for measuring weight of molten metal contained in the feeding component and generating weight signals accordingly; and a controller.

By setting an electric resistance of a trough to a value larger than an electric resistance of a molten metal stored in a storage space, in a non-driving state, a current is caused to flow along a first current path from one side wall of the pair of side walls to another side wall through the bottom wall, and in a driving state, a current is caused to flow through a second current path from the one side wall through a middle part of the first current path and bypass to the molten metal, and return to the first current path, and in the driving state, in the molten metal, causing the magnetic force lines running vertically and the current running horizontally to cross each other to generate a Lorentz force, and by the Lorentz force, driving and carrying the molten metal in the trough.
